The Seasonic Prime TX-1300 ATX 3.1 is the objective winner of this comparison, securing six spec victories against the ASUS ROG THOR 1200W Platinum III. The most significant advantage offered by the Seasonic unit is its SATA connector count, which provides a 125% increase over the ASUS alternative. This substantial lead in connectivity capacity establishes the Seasonic Prime TX-1300 ATX 3.1 as the superior choice for users requiring extensive hardware support.

Users who prioritize maximum peripheral connectivity should select the Seasonic Prime TX-1300 ATX 3.1 to take advantage of its superior SATA interface density. Conversely, the ASUS ROG THOR 1200W Platinum III remains a viable option for builds that do not require the additional SATA connections provided by its competitor. Choosing between these two power supplies depends entirely on whether your specific system configuration demands the higher connector count found in the Seasonic model.
